Roman warfare is not pretty. In the beginning of the Roman's siege of Jerusalem in 70 A.D. (predicted by Christ, mind you), the Romans were hurling artillery over the walls. At first they started with catapult stones; the Jewish rebels on the walls could see these coming, and would yell, "Baby on the way!" and dive for cover. The Romans realized they weren't making much progress (in other words: killing a lot of the enemy), so they painted their artillery black and started firing again. They weren't just hurling catapult stones; they also fired giant bolts from artillery weapons called ballistae and skorpions. Josephus, a historian who recorded some of the effects of the artillery, tells of seeing a man thrown a quarter of a mile away by the impact of a catapult stone. Even worse, he describes a bolt from a ballistae or skorpion that flew over the city walls and hit a pregnant woman (what the heck is she doing in the street during the Roman bombardment?); she is killed instantly, but this is the gruesome part: the bolt passed through her and tore her unborn baby out. You don't ever see this stuff in the movies, but it's how it really was. Warfare sure has changed a lot.
